Is it even possible to follow the wiki section "Modifying the X86_64 system" on a i686 install? I hope I have not overlooked something

I've seen that it's possible to do using static qemu by copying the binary into the chroot system: $ cp /usr/bin/qemu-arm archarm-chroot/usr/bin But despite this I always get the following error: chroot: failed to run command http://unix.stackexchange.com/questions/41889/how-can-i-chroot-into-a-filesystem-with-a-different-architechture ‘/bin/bash’: Exec format error I know this means that the architectures differ.

An example for configuring binfmt_misc can be found at svn.kju-app.org/trunk/qemu/qemu/qemu-binfmt-conf.sh –Ulrich Dangel Jun 28 '12 at 23:00 Qemu static packages don't appear to be in the Arch repositories. –Jivings Jun 28 '12 at 23:04 1 Sorry i don't use arch, but you should probably be able to build a static qemu package by adding -static to the linker options –Ulrich Dangel Jun 28 '12 at 23:07 add a comment| 6 Answers 6 active oldest votes up vote 11 down vote accepted You cannot chroot into different architecture. By chrooting, you are executing the binaries (from the chroot) on your architecture. Executing ARM binaries on x86 (and x86_64 in that matter) would lead to "Exec format error". If you want to run binaries from different architecture you will need an Emulator. Qemu is a good candidate for this, but you will need to learn how to use it. This would involve creating RootFS and compiling a

Its dual boot with windows and ubuntu. It fails to find OS, isntead of goijng to grub. It just stats loading operating system....boot error I am not sure why because it worked last night, but i didnt do anything change wise. So i got a live cd to reinstall grub the error i get when i try to chroot into my os from the live cd is chroot: failed to run command '/bin/bash': Exec format error the commands to chroot i am using are Code: sudo mount /dev/sda5 /mnt sudo mount -t proc none /mnt/proc sudo mount -o bind /dev /mnt/dev sudo mount -o bind /sys /mnt/sys sudo chroot /mnt sda5 is my linux partition This has always worked for me before. I am not sure why it cannot find bash? EDIT: i searched online and found someon
Boot a Sabayon Linux LiveCD/DVD or other Live disc. Get to a virtual terminal (console) or open a Konsole/Terminal window on the Desktop, and log-in as the root user. Make sure the LiveCD/DVD you use is for the same architecture as the architecture of the installation on the hard disk, i.e. to chroot to a 64-bit installation (e.g. amd64) you cannot use a 32-bit LiveCD/DVD (e.g. x86), and vice versa. You will see an error message "chroot: cannot run command `/bin/bash': Exec format error" if you try to chroot from a LiveCD/DVD of a different architecture. Whilst it is possible to mount filesystems from within the chrooted system, this is not recommended. The reason for this is that the LiveCD/DVD environment won't know about these mounted systems, so if you forget about them and leave them mounted when you exit from the chroot environment, they will not be unmounted properly when the system shuts down, which could cause damage to the filesystems on those mounts. Mount the root partition of the installed system (and, if you have /boot on a separate partition, mount that too). If separate partitions are used for other areas of the system (for example, a separate partition for /var/log) then you will need to mount them too. Additionally, mount the /dev and /proc filesystems so that they can be used by the chrooted environment. In the following example, /dev/hda1 is the /boot partition and /dev/hda3 is the root partition. Obviously replace those with the device names for your boot partition (if you have one) and your root partition. If your partition names are of the form /dev/sd
